“…Whether this greater similarity can be explained by interaction with and adaptation to the host (either plant or insect) is an open question. All four are thought to be transmitted by members of the genus Cacopsylla (order Homoptera, suborder Sternorrhyncha; superfamily Psylloidea; family Psyllidae), namely AP by C. costalis (Frisinghelli et al ., 2000) (although there is an earlier report of inefficient transmission by Fieberiella florii , a leaf‐hopper in the suborder Auchenorrhyncha, and the detection of AP in this insect by PCR; Bliefernicht and Krczal, 1995; Krczal et al. , 1988), ESFY by C. pruni (Carraro et al ., 1998, 2001; Jarausch et al ., 2001), PD by C. pyricola in North America and the UK (Davies et al ., 1992; Jensen et al ., 1964) and probably by C. pyri in southern Europe (Avinent et al ., 1997; Giunchedi et al ., 1994), and PYLR by C. pyricola (Blomquist and Kirkpatrick, 2002).…”

SUMMARY Homologues of the immunodominant membrane protein gene from apple proliferation (AP) phytoplasma have been cloned and sequenced for three further members of the AP subclade, namely European stone fruit yellows, peach yellow leaf roll and a European isolate of pear decline (PD). The putative translation products of all three were similar in size to that of AP and all had a transmembrane region towards the N‐terminus and a large C‐terminal hydrophilic domain, probably held on the outside of the cell membrane in vivo. Sequence similarities for the putative proteins were compared with interrelationships of the phytoplasmas as measured by rRNA gene sequence similarity. The proteins from AP and PD were more similar (57% identical in the major hydrophilic domain) than those for any other pair (31–34%), but these two phytoplasmas were not more closely related by rRNA gene sequences than other pairs. The possibility that the relative similarities of these proteins is related to the host is discussed. It is suggested that the similarity of the AP and PD proteins may reflect the fact that these two proteins have narrow plant host ranges in two closely related genera in the tribe Maloideae (family Rosaceae), whilst the other two have broader host ranges, mainly in the tribe Prunoideae.

“…The AP pathogen is mainly spread by two psyllids, Cacopsylla picta and C. melanoneura (Frisinghelli et al 2000;Tedeschi and Alma 2004). The leafhopper Fieberiella florii is also reported to vector the pathogen (Krczal et al 1988;Tedeschi and Alma 2006). Furthermore, infection via natural root grafts has been demonstrated (Ciccotti et al 2005).…”

In three trials carried out over a period of 24 years, open-pollinated seedlings of Malus sieboldii and M. sargentii and 22 apomictic rootstock selections with either M. sieboldii, M. sargentii or M. hupehensis in their parentage were examined for apple proliferation (AP) resistance in comparison to clonal M. x domestica-based rootstocks M 9, M 11, M 13, stocks of the B (Budagovski) and the Polish P series and M. robusta seedlings. Following experimental inoculation or natural infection the Golden Delicious-grafted trees on most of the M. sieboldii-derived progenies showed a high level of AP resistance expressed by low cumulative disease indices, a high percentage of non or little affected trees, low incidence of the small fruit symptom and non or little effect on vigour. Trees on M 9 and M 11, B 118 and M. robusta seedlings were moderately susceptible while trees on progenies with M. sargentii and M. hupehensis parentage, rootstocks of the P series, B 9, B 490 and M 13 proved highly susceptible. The screening also showed that rootstocks with M. sieboldii and M. sargentii parentage are often highly susceptible to latent apple viruses. Trees on most of the M. sieboldii-based progenies were more vigorous than trees on standard stock M 9, whereas the vigour of some progenies from selections with M. sargentii parentage was in the range of M 9 or even lower. Productivity was often correlated with the vigour.

“…P. mali is transmitted in a persistent manner by Cacopsylla picta (Carraro et al 2001) and C. melanoneura (Tedeschi et al 2002). The role of leafhopper Fieberiella flori as a vector of this phytoplasma was also discussed (Krczal et al 1989;Tedeschi, Alma 2006). Ca.…”

Cieślińska M., Kruczyńska D.E., 2014. Detection and molecular characterization of phytoplasmas infecting apple trees in Poland. Hort. Sci. (Prague), 41: 27-33.During 2010-2012, samples from 225 apple trees growing in six regions of Poland were tested for phytoplasmas. 16S rRNA gene and 16S-23S spacer region sequences were amplified from total DNAs prepared from phloem tissue of apple shoots. According to the results of PCR-RFLP and sequence analyses, apple trees were infected by Candidatus Phytoplasma mali and Ca. P. asteris. Fragments of 16S rDNA plus 16S-23S spacer region of the Ca. P. mali isolates digested with HpaII enzyme showed two restriction profiles: P-I and P-II. Multiple alignments of 16S rRNA gene fragments revealed that the isolates of Ca. P. mali shared 100% sequence identity among themselves as well as with reference strains AT and AP-15 of apple proliferation phytoplasma. The nucleotide sequence of the same region of Ca. P. asteris isolates confirmed the phylogenetic relationship with reference strains OAY (MIAY) and AY1 of aster yellows phytoplasma PCR-RFLP analysis of ribosomal protein (rpl22 and rpS3), secY, and tuf genes did not show the sequence diversity of the isolates of aster yellows phytoplasma.
